I have logged into my Trello account using three different browsers - Edge, Chrome, and Safari. I have also taken the steps suggested to clear the cache and to adjust cookie settings, and yet, when I log in the screen remains a variegated pink/purple with the Trello logo in the top left corner. The url is simply: trello.com/welcome-to-trello. There is nothing to click. This has been an issue since signing up a month ago.
